This invention relatesto cloth pads for duplicating machines, and especially to those.

for use on the mimeograph. As is well known, in machines for mak- 5 ing ink copies, and particularly where a stencil is used on a rotary cylinder, it has been the practice to use a cloth pad on the cylinder to hold the ink which is to be transmitted i it secure them to the inking cylinders. In this practise there are a number of disadvantages, among which are a tendency of the ink to flow to the side edges of the pad and to seep therebeyond, tearing of the pad adjacent the ends of the metal strips, and a-looseness or fullness in certain arts of the sheet where it may be undesira le.

"The princi a1 object of the present invention is, theref re, to provide an ink pad which does not possess these disadvantages.

A further object is the production of a pad which makes for a cleaner surface on the inking cylinder and which efiects a more evenly printed copy.

Another object is the provision of a ad which is simple and inexpensive to manu acture and whose length of service is greatly increased.

Other and further objects and advantages I of the present invention will-appear from the following detailed description of the preferred embodiments thereof, reference being had to the accom anying drawings.

I have found t at by stitching or preferably binding, the edges of an ink pad, there is produced a pad which avoids these disadvantages of the prior art, and one which is not only more durable and serviceable but one which also prevents ink from extruding or seeping beyond the edges of the pad.

Fig. l is a plan view of an ink pad in accordance with the present invention; Fig. 2 is a plan view of a modified torm of the inventlon; Fig. 3 is an enlarged section taken so on the lines 3-3 of Fig.2; ig. 4 is a section '1930. Serial H0. 444,883.

shown as a double row of stitching, but any other suitable stitching may be rovided.

In the modification shown in 1g. 2, the

ink pad 1, is provided with bindings 7, along the full length of each edge. These bindings may bestitched to the pad as at 8. This modification'is often, preferred in many instances. to the one shown in Fig. 1. Y

The advantages of my improved ink ad are mainly apparent from the above. hveral special advantages, however, reside in the ability of my pad to be drawn down tightly along its edges when applied to the inking cylinder. This not only cumulatively aids the binding or stitching in preventing the seeping out of the ink, but also permits ofa slight fullness of the pad at its center portions just where'it is desirable in order that the ink be properly distributed to give an evenly printed copy. That is, not only is the flow ofink to the edges decreased, but the needed ink is distributed well in the center 4 of the pad.

What I claim is 1. An ink pad having rigid strips traversing its respective ends and attached thereto and stitching along the side edges of the pad.

' 2. A cloth ink pad having transverse rigid strips attached to itsrespective ends and adapted to secure the pad to an' inking cylinder, and binding along substantially the full length of each side'edge of the pad. I 3. An ink pad for a rotary cylinder duplicating machine having rigid strips transversand attached to its respective ends and flexible and substantially inextensible binding means carried along the side edges-0f the pad and secured to the rigid strips to tightly engage said sideedges with the rotary oilinder and thereby prevent seepage of ink mm the center of the pad to and past said edges.

4. A cloth ink pad having transverse rigid strips arranged to grip its end edges and adapted to secure the ad to an inking cylinder, and flexible cloth inding alon substantially the full length of each side ge of the ad. p 5. A cloth ink pad having transverse rigid strips arranged to grip its end edges and adapted to secure the'gad to an inking cylinder' and having clot binding along each side edge of the pad, the ends of the binding being gripped by said strips.

6. An 'ink pad having flexible binding along each side edge, and rigid binding alon its end ed es arranged to ip the pad an the ends 0 the flexi le bin 'ngi ERNEST JOSEPH B ASSEUR.
